'anaplerosis' originates from Greek, specifically the word 'anaplērōsis', where 'ana-' meant 'again' and 'plēroun' meant 'to fill'.

'anaplerosis' was adopted into New Latin from the Greek 'anaplērōsis', and eventually became the modern English word 'anaplerosis'.

Initially, it meant 'filling up again', and over time it evolved into its current meaning of 'replenishment or restoration, especially in biological or rhetorical contexts'.
